Wasomi wa Physics naomba majibu

Or shortly ni Kwamba hakuna consumption coz the circuit is not completed. It is still an open cct.

Umeme ni neno kubwa sana. Hapa lazima tuangalie vitu vitatu ambavyo ni Load (Resistance R) eg. Bulb hiyo uliosema, Voltage V na Current I. Kwahiyo mkuu kama ukiwasha switch ni kwamba Voltage V itafika mpaka point of connection ya bulb lakini current I haiwezi kuwepo. Na Voltage itafika ileile ya supply let say 240Vac kwakuwa voltage in parallel is equal. Nakumbuka kuwa voltage hapa ni kama force ya kusukuma electrical charge ambayo ni current panapokuwa na Resistance R.
Kwakifupi
1. Umeme (voltage) utafika mpaka point of connection
2. Current haitakuwepo kwakuwa hakuna load (bulb)
3. Mita yako haitatembea kwakuwa no current drawn.

Kama una swali lingine la umeme uliza usiogope!!

DarKwetu, what pushes the electrons ni ELECTROMOTIVE FORCE (EMF) na si switch ndo maana nikakwambia inategemea na factors nyingi ikiwemo:
1. Aina ya sakiti kama ni sambamba ama mfuatano

2. Aina ya umeme kama ni D.C. au A.C.

aina gani ya circuit? Umemsoma Kirchoff kweli wewe?

umechanganya electromotive force na voltage! PITIA CHAND AU UNIVERSITY PHYSICS (U. P.)

Umeme hautumiki, na bill haiendi. Period. Tatizo Waswahili wengine mnapenda sana ku-complicate mambo ili kujifanya mnajua zaidi.

Wewe "uliyemsoma" Kirchoff tuambie anasema nini kuhusu hii issue. Kirchoff's Law haina uhusiano wowote kuhusu hili.
